Abstract
A downhole wireline tool string has an electric motor powered through a wireline for providing rotational output, a tool section for anchoring the downhole wireline tool string inside a well tubular metal structure, an operational tool rotated by the rotational output and defining the front end and an end surface arranged axially opposite the wireline and having an annular wall with a circumference and a wall thickness defined by an inner wall radius and an outer wall radius from the centre tool axis. The operational tool comprises a first grinding section having an inner face being arranged at a first distance from the centre tool axis, the first distance being smaller than the inner wall radius, and a second grinding section having an outer face being arranged at a second distance from the centre tool axis, the second distance being greater than the outer wall radius.
